Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a so-called ozonizer for supplying a gas such as air or oxygen to a silent corona discharge area and producing ozone gas from the gas.

Conventional technology Conventionally, this type of ozonizer has a pair of electrodes connected through an air or oxygen gas passage and a dielectric layer. In addition to generating a corona discharge, air or oxygen gas is supplied to the passage to convert it into ozone gas.

The power efficiency of osone generation at this time is extremely low, only a few percent. In other words, most of the power consumed becomes heat, which increases the temperature of each electrode, dielectric, gas, etc., and this temperature increase reduces the density of scum and increases the effectiveness of ozone gas generation. Lower the area.

In order to prevent this, until now each of the electrodes has been cooled with a cooling medium such as air.

Problems to be Solved by the Invention When each electrode is cooled with a cooling liquid, the properties of the ozonizer are
Since a high-voltage AC power source is used, it is generally difficult to ensure insulation.

The difficulty is particularly significant when water is used as the cooling medium.

The purpose of the present invention is to prevent the generation of ozone gas in young cattle due to temperature rise in the conventional ozonizer as described above, and to prevent the temperature rise by using water as a cooling medium. The main purpose is to ensure the insulation of the electrodes of ozona and rza.

In order to solve the problem, a liquid refrigerant chamber was provided in one part of the first stage ozonation zone using a planar rod, and a liquid electrode was formed on the other side via a planar dielectric body. A high-voltage AC power source is connected between the three-sided electrode and the liquid electrode, and the liquid refrigerant chamber is connected to the insulated outer wire J (an electric resistance formed by the refrigerant in the tube), and the It is characterized in that it is grounded and the liquid electrode mentioned above is also grounded.

Operation: High-voltage alternating current from the above-mentioned high-voltage alternating current power supply is applied between the planar electrode and the liquid electrode to generate a silent corona discharge in the ozonized region existing between the two electrodes. At the same time, a gas to be ozonated, such as air or oxygen, is injected into the ozonization zone, and the silent corona discharge is applied to this gas, thereby ozonizing it.

At this time, the planar electrode is cooled by the liquid supplied into the liquid refrigerant chamber that is in contact with it, and the liquid electrode is cooled by cooling the liquid itself supplied from the outer refrigerant [-1]. .

In this way, the gas to be ozonated flowing through the ozonation zone is cooled from its inner and outer sides and is ozonized at a low temperature.

Embodiment An embodiment of the present invention will be described with reference to the accompanying drawings. A liquid refrigerant chamber 3 is provided inside a cylindrical ozonation zone 1 via a cylindrical planar electrode 2, and a cylindrical dielectric 4 is provided on the outside. A cylindrical liquid electrode 5 is provided concentrically through the liquid refrigerant chamber 3, and a high voltage, AC power source 6 is connected between the planar electrode 2 and a cylindrical wire mesh conductor 5a immersed inside the liquid electrode 5. One end of the coiled cooling pipe 8 formed of an insulating long tube is connected to the refrigerant pipe 17 at one end through a circulation vibrator 9, and the other end of the coiled cooling pipe 8 is connected to the refrigerant pipe 17 of the liquid refrigerant chamber 3. Liquid output 1 at the other end
10 is connected to another circulation vibe 11, and a coiled cooling pipe 8 is connected to the coiled cooling pipe 8.
This is an ozonizer in which a liquid refrigerant flows into the ozonizer to form an electric resistance 12, and the midpoint 12a of the electric resistance and the liquid electrode 5 are grounded 1.3 and 14, respectively.

An AC voltage is applied between the planar mold g2 and the liquid electrode 5 by a high-voltage AC source via the cylindrical wire mesh conductor 5a to generate a corona discharge in the ozonization zone 1, and
In the ozonization zone 1, a gas pump 15, a gas vibrator 1
6 and the gas to be ozonated such as oxygen sent through the gas inlet 17, and take it out as ozone scum 19 through the scum outlet 20, the ozone gas vibrator 21, and the ozone gas pressure regulating valve 22. be.

At this time, the liquid refrigerant chamber 3 inside the planar electrode 2 has a refrigerant [
The ozonation zone 1 is cooled from the inside by supplying a coolant such as water or oil from 17, and the liquid electrode 5 outside the ozonization zone 1 is cooled by liquid fed from the outside liquid inlet 23. , the ozonation effect in the ozonization zone 1 is performed at a low temperature to improve its efficiency.

Also, the refrigerant supplied from the refrigerant man n7 mentioned above is the cooling M2
The refrigerant is cooled as it passes through the coiled cooling pipe 8 immersed in the cooling liquid 25 such as water or oil in the cooling fluid 25 inside the coiled cooling pipe 8 , and is discharged from the refrigerant outlet 10 through the circulation vibrator 11 .
111 and is cooled. Reference numeral 27 denotes a refrigerant pump that is interposed between the installation ground portions 12a, 12a in the middle of the cooling pipe 8.

At this time, the planar electrode 2 is grounded through an electric resistance 12-X made up of the refrigerant in the liquid refrigerant chamber 3 and the refrigerant in the coiled cooling tube 8, thereby narrowing the path of the refrigerant in the coiled cooling tube 8.
(2) By making it sufficiently long, the electric resistance value can be increased and the leakage current from the planar electrode 2 can be kept extremely small.

Further, the liquid supplied from the outer liquid input I23 is sent through a liquid pump 28, a cooler 29, and a liquid pipe 30, and the liquid discharged from the liquid outlet 31 is returned to the liquid pump 28 described above.

Note that 32 is a casing, and 33 is a cooling fin.

Effects This invention has the advantage that the ozonation zone is cooled from the inside by the liquid in the liquid refrigerant chamber, and is effectively cooled from the outside by the liquid electrode, so that the temperature of the ozonation zone does not rise. Ozone can be generated at low temperatures, and its generation efficiency is not hindered by temperature increases.

Further, since the present invention has the above-mentioned configuration, when water is used as the refrigerant, the cooling efficiency is extremely good and it is economical.

In particular, since the liquid refrigerant chamber and the electrical resistance formed by the refrigerant in the insulating elongated tube are connected and grounded via the electrical resistance, the planar electrode facing the liquid refrigerant chamber The insulation properties of the electrodes can be ensured, and the liquid refrigerant can be circulated for cooling while keeping the leakage current from the planar electrodes extremely small.
